First-line nurse managers are more likely to work according to gender beliefs and stereotypes, which may affect their managerial competence. This study is aimed at comparing managerial competence of male and female first-line nurse managers in public hospitals in Indonesia.

Distal symmetric polyneuropathy (DSP) is the most common variety of neuropathy. Since the evaluation of this disorder is not standardized, the available literature was reviewed to provide evidence-based guidelines regarding the role of autonomic testing, nerve biopsy, and skin biopsy for the assessment of polyneuropathy. A literature review using MEDLINE, EMBASE, Science Citation Index, and Current Contents was performed to identify the best evidence regarding the evaluation of polyneuropathy published between 1980 and March 2007. Articles were classified according to a four-tiered level of evidence scheme and recommendations were based on the level of evidence. (1) Autonomic testing may be considered in the evaluation of patients with polyneuropathy to document autonomic nervous system dysfunction (Level B). Such testing should be considered especially for the evaluation of suspected autonomic neuropathy (Level B) and distal small fiber sensory polyneuropathy (SFSN) (Level C). A battery of validated tests is recommended to achieve the highest diagnostic accuracy (Level B). (2) Nerve biopsy is generally accepted as useful in the evaluation of certain neuropathies as in patients with suspected amyloid neuropathy, mononeuropathy multiplex due to vasculitis, or with atypical forms of chronic inflammatory demyelinating polyneuropathy (CIDP). However, the literature is insufficient to provide a recommendation regarding when a nerve biopsy may be useful in the evaluation of DSP (Level U). (3) Skin biopsy is a validated technique for determining intraepidermal nerve fiber (IENF) density and may be considered for the diagnosis of DSP, particularly SFSN (Level C). There is a need for additional prospective studies to define more exact guidelines for the evaluation of polyneuropathy. Muscle Nerve 39: 106-115, 2009. [ABSTRACT FROM AUTHOR]

Distal symmetric polyneuropathy (DSP) is the most common variety of neuropathy. Since the evaluation of this disorder is not standardized, the available literature was reviewed to provide evidence-based guidelines regarding the role of laboratory and genetic tests for the assessment of DSP. A literature review using MEDLINE, EMBASE, Science Citation Index, and Current Contents was performed to identify the best evidence regarding the evaluation of polyneuropathy published between 1980 and March 2007. Articles were classified according to a four-tiered level of evidence scheme and recommendations were based on the level of evidence. (1) Screening laboratory tests may be considered for all patients with polyneuropathy (Level C). Those tests that provide the highest yield of abnormality are blood glucose, serum B(12) with metabolites (methylmalonic acid with or without homocysteine), and serum protein immunofixation electrophoresis (Level C). If there is no definite evidence of diabetes mellitus by routine testing of blood glucose, testing for impaired glucose tolerance may be considered in distal symmetric sensory polyneuropathy (Level C). (2) Genetic testing is established as useful for the accurate diagnosis and classification of hereditary neuropathies (Level A). Genetic testing may be considered in patients with cryptogenic polyneuropathy who exhibit a hereditary neuropathy phenotype (Level C). Initial genetic testing should be guided by the clinical phenotype, inheritance pattern, and electrodiagnostic (EDX) features and should focus on the most common abnormalities, which are CMT1A duplication/HNPP deletion, Cx32 (GJB1), and MFN2 mutation screening. There is insufficient evidence to determine the usefulness of routine genetic testing in patients with cryptogenic polyneuropathy who do not exhibit a hereditary neuropathy phenotype (Level U).

Smoking is a major risk factor for many chronic diseases. Nearly all studies collecting smoking data use self-reports, which are very rarely validated. We identified 15,182 adults 18 years or older in the Third National Health and Nutrition Examination Survey. Denying smoking, the main outcome, was defined as cotinine-determined smokers self-reporting non-smoking. Multiple logistic regression modeling took into account the complex survey design and sample weights. Age and race/ethnicity-gender categories predicted denying smoking. Smokers denying smoking ranged from 0.0% for elderly (75 years and older) Mexican-American women to 67.8% for elderly non-Hispanic Black women. Among elderly smokers, non-Hispanic Black women were more likely to deny smoking than both non-Hispanic White women (odds ratio (OR) = 8.9, 95% confidence interval (CI): 2.1-38.3) and non-Hispanic Black men (OR=21.4 95% CI: 4.3-107.2). This U.S. population-based study of age-specific race/ethnicity-gender predictors of denying smoking suggests caution in interpreting smoking-related survey data. [ABSTRACT FROM AUTHOR]

BACKGROUND: Chronic kidney disease, undiagnosed in a significant number of adults, is a public health problem. Given the systemic inflammatory response to periodontal disease, we hypothesized that periodontal disease could be associated with chronic kidney disease. STUDY DESIGN: Cross-sectional. SETTING & PARTICIPANTS: We identified 12,947 adults 18 years or older with information for kidney function and at least one risk factor in the Third National Health and Nutrition Examination Survey. PREDICTOR: The main predictor was periodontal status. Other nontraditional and traditional risk factors included socioeconomic status, health status, health behavior, biomarker levels, anthropometric assessment, and health care utilization. OUTCOMES & MEASUREMENTS: Chronic kidney disease was defined using the Kidney Disease Outcomes Quality Initiative stages 3 and 4 with a moderate to severe decrease in kidney function (glomerular filtration rate, 15 to 59 mL/min/1.73 m(2)). Univariable and multivariable logistic regression models assessed the associations between chronic kidney disease and periodontal disease and other nontraditional risk factors. RESULTS: Chronic kidney disease prevalence was 3.6%; periodontal disease prevalence was 6.0%; and edentulism prevalence was 10.5%. Adults with periodontal disease and edentulous adults were twice as likely to have chronic kidney disease (adjusted odds ratio, 1.60; 95% confidence interval, 1.16 to 2.21; adjusted odds ratio, 1.85; 95% confidence interval, 1.34 to 2.56, respectively) after simultaneously adjusting for other traditional and nontraditional risk factors. LIMITATIONS: Temporal association is unknown. CONCLUSIONS: Periodontal disease and its severe consequence, edentulism, were independently associated with chronic kidney disease after adjusting for other traditional and nontraditional risk factors. This model could contribute to identifying individuals at risk of chronic kidney disease and reduce its burden. Copyright © 2008 National Kidney Foundation, Inc. [ABSTRACT FROM AUTHOR]

The Centers for Disease Control and Prevention (CDC) released new guidelines for the treatment of sexually transmitted diseases (STDs) in 1998. Several treatment advances have been made since the previous guidelines were published. Part II of this two-part series on STDs describes recommendations for the treatment of diseases characterized by vaginal discharge, pelvic inflammatory disease, epididymitis, human papillomavirus infection, proctitis, proctocolitis, enteritis and ectoparasitic diseases. Single-dose therapies are recommended for the treatment of several of these diseases. A single 1-g dose of oral azithromycin is as effective as a seven-day course of oral doxycycline, 100 mg twice a day, for the treatment of chlamydial infection. Erythromycin and ofloxacin are alternative agents. Four single-dose therapies are now recommended for the management of uncomplicated gonococcal infections, including 400 mg of cefixime, 500 mg of ciprofloxacin, 125 mg of ceftriaxone or 400 mg of ofloxacin. Advances in the treatment of bacterial vaginosis also have been made. A seven-day course of oral metronidazole is still recommended for the treatment of bacterial vaginosis in pregnant women, but intravaginal clindamycin cream and metronidazole gel are now recommended in nonpregnant women. Single-dose therapy with 150 mg of oral fluconazole is a recommended treatment for vulvovaginal candidiasis. Two new topical treatments, podofilox and imiquimod, are available for patient self-administration to treat human papillomavirus infection. Permethrin cream is now the preferred agent for the treatment of pediculosis pubis and scabies. [ABSTRACT FROM AUTHOR]

In 1998, the Centers for Disease Control and Prevention released guidelines for the treatment of sexually transmitted diseases. Several treatment advances have been made since the previous guidelines were published. Part I of this two-part article describes current recommendations for the treatment of genital ulcer diseases, urethritis and cervicitis. Treatment advances include effective single-dose regimens for many sexually transmitted diseases and improved therapies for herpes infections. Two single-dose regimens, 1 g of oral azithromycin and 250 mg of intramuscular ceftriaxone, are effective for the treatment of chancroid. A three-day course of 500 mg of oral ciprofloxacin twice daily may be used to treat chancroid in patients who are not pregnant. Parenteral penicillin continues to be the drug of choice for treatment of all stages of syphilis. Three antiviral medications have been shown to provide clinical benefit in the treatment of genital herpes: acyclovir, valacyclovir and famciclovir. Valacyclovir and famciclovir are not yet recommended for use during pregnancy. Azithromycin in a single oral 1-g dose is now a recommended regimen for the treatment of nongonococcal urethritis.

Abstract Background Physician reporting is commonly used to ascertain adverse events or outcomes measured in epidemiologic studies. However, little is known on the accuracy of physician reported malignancies compared to pertinent medical record review in large cohort studies. Methods The Consortium of Rheumatology Researchers of North America (CORRONA) registry gathers physician-completed questionnaires for rheumatoid arthritis (RA) patients, including request for information on incident malignancies, approximately every three months. For incident malignancies reported from October 1st, 2001, through December 31st, 2007, we retrospectively requested completion of a Targeted Adverse Event (TAE) form for additional information as well as primary source documents to adjudicate the malignancy reports. CORRONA has employed a prospective request for source documentation for these events since 2008. We classified each malignancy as definite, probable, possible, or not a malignancy. Results From 20,837 RA patients enrolled in CORRONA, 461 incident malignancies were initially reported on physician questionnaires. After review of returned source documents with adjudication, 234 were deemed definite, 69 probable, 101 possible, and 57 not an incident malignancy. The positive predictive value (PPV) of initial physician report of a malignancy versus “definite or probable” malignancy based on adjudication was 0.66 (95% CI 0.61 - 0.70). The PPV was 0.68 (95% CI 0.63 – 0.72) when the subsequent TAE form also confirmed the presence of malignancy. When possible malignancies were included, the PPV of physician-reported malignancies without a subsequent TAE form increased to 0.86 (0.83 – 0.89), and with a subsequent TAE form, 0.89 (0.85-0.91). Conclusion Twelve percent of initial physician reports of incident malignancy could not be confirmed with review of source documents. The most common reason for lack of confirmation was inability to obtain documents or insufficient data in source materials. These results suggest that timely collection of relevant medical records and an adjudication process are required to improve the accuracy of cancer reporting in epidemiologic studies.

Abstract Background Post-exposure prophylaxis (PEP) following sexual exposure to HIV has been recommended as a method of preventing HIV infection in the UK. Men who have sex with men (MSM) are the group most affected by HIV in the UK and their sexual risk taking behaviour is reported to be increasing. One-to-one behavioural interventions, such as motivational interviewing (MI) have been recommended to reduce HIV in high risk groups. The Information, Motivation and Behavioral skills (IMB) model has been shown to provide a good basis for understanding and predicting HIV-relevant health behaviour and health behaviour change, however the IMB has yet to be applied to PEP after risky sexual exposure. The primary aim of this trial is to examine the impact of MI augmented with information provision and behavioural skills building (informed by the IMB Model), over and above usual care, on risky sexual behaviour in MSM prescribed PEP after potential sexual exposure. A secondary aim of this research is to examine the impact of the intervention on adherence to PEP. This study will also provide estimates of the cost-effectiveness of the intervention. Methods A manualised parallel group randomised controlled trial with economic evaluation will be conducted. The primary outcome is the proportion of risky sexual practices. Secondary outcomes include: i) Levels of adherence to PEP treatment; ii) Number of subsequent courses of PEP; iii) Levels of motivation to avoid risky sexual behaviours; iv) Levels of HIV risk-reduction information/knowledge; v) Levels of risk reduction behavioural skills; vi) Diagnosis of anal gonorrhoea, Chlamydia and/or HIV. 250 participants will be asked to self-complete a questionnaire at four time points during the study (at 0,3,6,12 months). The intervention will consist of a two-session, fixed duration, telephone administered augmented MI intervention based on the IMB model. A newly developed treatment manual will guide the selection of persuasive communication strategies as appropriate for each participant and will be based on underlying change mechanisms specified by the IMB theoretical framework. Information provision and skills building will also be included in the intervention package through the use of information leaflets and tailored action plans. Fidelity of intervention delivery will be assessed. Discussion The results from this NIHR funded study will identify whether it is appropriate and cost-effective to intervene using one-to-one telephone calls with MSM seeking PEP. If the intervention is effective, further work will be needed on training staff to deliver the intervention competently. Trial registration numbers UKCRN ID:11436; ISRCTN00746242.

Abstract Background Mesophotic corals (light-dependent corals in the deepest half of the photic zone at depths of 30 - 150 m) provide a unique opportunity to study the limits of the interactions between corals and endosymbiotic dinoflagellates in the genus Symbiodinium. We sampled Leptoseris spp. in Hawaii via manned submersibles across a depth range of 67 - 100 m. Both the host and Symbiodinium communities were genotyped, using a non-coding region of the mitochondrial ND5 intron (NAD5) and the nuclear ribosomal internal transcribed spacer region 2 (ITS2), respectively. Results Coral colonies harbored endosymbiotic communities dominated by previously identified shallow water Symbiodinium ITS2 types (C1_ AF333515, C1c_ AY239364, C27_ AY239379, and C1b_ AY239363) and exhibited genetic variability at mitochondrial NAD5. Conclusion This is one of the first studies to examine genetic diversity in corals and their endosymbiotic dinoflagellates sampled at the limits of the depth and light gradients for hermatypic corals. The results reveal that these corals associate with generalist endosymbiont types commonly found in shallow water corals and implies that the composition of the Symbiodinium community (based on ITS2) alone is not responsible for the dominance and broad depth distribution of Leptoseris spp. The level of genetic diversity detected in the coral NAD5 suggests that there is undescribed taxonomic diversity in the genus Leptoseris from Hawaii.

Abstract Ligaments and tendons are soft connective tissues which serve essential roles for biomechanical function of the musculoskeletal system by stabilizing and guiding the motion of diarthrodial joints. Nevertheless, these tissues are frequently injured due to repetition and overuse as well as quick cutting motions that involve acceleration and deceleration. These injuries often upset this balance between mobility and stability of the joint which causes damage to other soft tissues manifested as pain and other morbidity, such as osteoarthritis. The healing of ligament and tendon injuries varies from tissue to tissue. Tendinopathies are ubiquitous and can take up to 12 months for the pain to subside before one could return to normal activity. A ruptured medial collateral ligament (MCL) can generally heal spontaneously; however, its remodeling process takes years and its biomechanical properties remain inferior when compared to the normal MCL. It is also known that a midsubstance anterior cruciate ligament (ACL) tear has limited healing capability, and reconstruction by soft tissue grafts has been regularly performed to regain knee function. However, long term follow-up studies have revealed that 20–25% of patients experience unsatisfactory results. Thus, a better understanding of the function of ligaments and tendons, together with knowledge on their healing potential, may help investigators to develop novel strategies to accelerate and improve the healing process of ligaments and tendons. With thousands of new papers published in the last ten years that involve biomechanics of ligaments and tendons, there is an increasing appreciation of this subject area. Such attention has positively impacted clinical practice. On the other hand, biomechanical data are complex in nature, and there is a danger of misinterpreting them. Thus, in these review, we will provide the readers with a brief overview of ligaments and tendons and refer them to appropriate methodologies used to obtain their biomechanical properties. Specifically, we hope the reader will pay attention to how the properties of these tissues can be altered due to various experimental and biologic factors. Following this background material, we will present how biomechanics can be applied to gain an understanding of the mechanisms as well as clinical management of various ligament and tendon ailments. To conclude, new technology, including imaging and robotics as well as functional tissue engineering, that could form novel treatment strategies to enhance healing of ligament and tendon are presented.

Abstract Background The selection of agents for any treatment regimen is in part influenced by physician and patient attitudes. This study investigated attitudinal motivators and barriers to the use of self-injectable antiretroviral agents among physicians and patients and measured the degree of concordance between physician and patient perspectives. Methods Attitudes toward prescribing and usage of self-injectable antiretroviral therapy (SIAT) were assessed by structured interview in 2 cohorts sampled from the European Union and the USA: 499 HIV-treating physicians and 603 treatment-experienced HIV-infected patients. Motivators and barriers to prescribing SIAT were identified from statistical analysis of the associations between physicians' ratings of enfuvirtide-based therapy compared to standard oral-based therapy and 2 indicators of enfuvirtide prescribing behavior. Patients' attitudes were assessed by their responses to a written profile of enfuvirtide and their ratings of the likelihood of accepting a treatment offer. Results Both indicators of SIAT prescribing behavior were predicted by the same pattern of physician beliefs. Nonprescribing was associated with: (1) the belief that offering enfuvirtide would be perceived negatively by patients, leading to treatment refusal and nonadherence; (2) the belief that prescribing enfuvirtide is harder to justify in terms of time/resources; and (3) a lack of confidence in the efficacy and use of enfuvirtide in practice (all p < 0.05). However, physicians' beliefs were not in concordance with patients' views. After reading a profile of enfuvirtide, 76% patients said that they would be moderately or highly likely to accept a treatment offer, although most (72%) had not discussed enfuvirtide with their doctor. Patients' beliefs predicted the likelihood of accepting enfuvirtide. Conclusion Physician and patient beliefs about SIAT influence prescribing behavior and compliance yet may not be concordant, with patients having more positive attitudes towards SIAT than anticipated by physicians.

Abstract Since its introduction approximately seven years ago, selamectin (Stronghold®/Revolution®, Pfizer Inc.) has been used off-label to treat a number of ecto- and endoparasite conditions in dogs and cats. It has been used as a successful prophylactic against Dirofilaria repens and as a treatment for Aelurostrongylus abstrusus in cats. It has also been used to treat notoedric mange, infestation with the nasal mite Pneumonyssoides caninum, Cheyletiella spp. and Neotrombicula autumnalis infestations and larval Cordylobia anthropophaga infection. However, to date attempts to treat generalised canine demodicosis have not been successful. In all cases, treatment was apparently well tolerated by the host.

Abstract Background Natural populations of the teleost fish Fundulus heteroclitus tolerate a broad range of environmental conditions including temperature, salinity, hypoxia and chemical pollutants. Strikingly, populations of Fundulus inhabit and have adapted to highly polluted Superfund sites that are contaminated with persistent toxic chemicals. These natural populations provide a foundation to discover critical gene pathways that have evolved in a complex natural environment in response to environmental stressors. Results We used Fundulus cDNA arrays to compare metabolic gene expression patterns in the brains of individuals among nine populations: three independent, polluted Superfund populations and two genetically similar, reference populations for each Superfund population. We found that up to 17% of metabolic genes have evolved adaptive changes in gene expression in these Superfund populations. Among these genes, two (1.2%) show a conserved response among three polluted populations, suggesting common, independently evolved mechanisms for adaptation to environmental pollution in these natural populations. Conclusion Significant differences among individuals between polluted and reference populations, statistical analyses indicating shared adaptive changes among the Superfund populations, and lack of reduction in gene expression variation suggest that common mechanisms of adaptive resistance to anthropogenic pollutants have evolved independently in multiple Fundulus populations. Among three independent, Superfund populations, two genes have a common response indicating that high selective pressures may favor specific responses.

Abstract Background Anaphylactoid reactions to iodinated contrast media are relatively common and potentially life threatening. Opinion is divided as to the utility of medications for preventing these reactions. We performed a systematic review to assess regimes for the prevention of anaphylactoid reactions to iodinated contrast media. Methods Searches for studies were conducted in the Medline, EMBASE, CINAHL and CENTRAL databases. Bibliographies of included studies and review articles were examined and experts were contacted. Randomised clinical trials that examined agents given prior to iodinated contrast material for the prevention of anaphylactoid reactions were included in the review. The validity of the included studies was examined using a component approach. Results Six studies met the inclusion criteria, but only one of these fulfilled all of the validity criteria. There were four studies that examined the use of H1 antihistamines, each was used to prevent anaphylactoid reactions to ionic contrast. The random effects pooled relative risk demonstrated a significant reduction in the overall rate of anaphylactoid reactions (RR = 0.4, 95% CI 0.18-0.9, p = 0.027). There were insufficient studies to produce a pooled statistic for the use of corticosteroids, however regimes of steroids (methylprednisolone 32 mg) given at least six hours and again two hours prior to the administration of contrast suggested a reduction in the incidence of anaphylactoid reactions. Conclusion In conclusion, there are few high quality randomised clinical trials that have addressed the question of the optimal methods to prevent allergic type reactions to iodinated radiological contrast media. Allowing for these limitations, the results suggest that H1 antihistamines given immediately prior to the administration of ionic contrast may be useful in preventing reactions to ionic contrast and are suggestive of a protective effect of corticosteroids when given in two doses at least six hours prior and again two hours prior to the administration of contrast, both ionic and non-ionic. These agents should be considered for use in patients who are at high risk of an anaphylactoid reaction to contrast media and for who prophylactic therapy is considered necessary. Further research is needed before definitive recommendations can be made.

The menopause transition and post-menopause period marks a time of dynamic physiological and hormonal change. Cisgender women commonly experience vasomotor symptoms, genitourinary symptoms, and changes in bone health. The transgender population, including those assigned female at birth (AFAB) and those assigned male at birth (AMAB), has been understudied in terms of experiences through the menopause transition and midlife. Additionally, there is no formal recommendation or guidance on continuation of gender-affirming hormone therapy (GAHT) through midlife. While gender-affirming therapies for transgender patients are well defined and supported by organizational guidelines, including from the World Professional Association for TGD Health (WPATH) (Standards of Care 8, SOC8) and from the Endocrine Society (2017), evidence on continuation of therapy and dose adjustments into mid-life are lacking. Data from a few large cohort studies and small cross-sectional studies suggest increased risk of venous thromboembolism (VTE), stroke and myocardial infarction in those AMAB on GAHT. For those AFAB on testosterone therapy, risks of cardiovascular disease and stroke and to bone health are not well defined, given inconsistent findings from large cohort studies. Currently, the decision to continue GAHT for transgender patients is guided by patient preference along with clinician guidance. Further research is warranted regarding risks of continuing GAHT into mid-life for both AMAB and AFAB patients. Given the significant benefit of GAHT in this population, however, this data would be most helpful for counseling on risks along with appropriate monitoring and prevention for related morbidities during mid-life in the setting of GAHT use., Competing Interests: Declaration of competing interest The authors declare that they have no competing interest., (Copyright © 2024 Elsevier B.V.

Chlamydia is an obligate intracellular bacterial pathogen responsible for disease and infertility across multiple species. Currently vaccines are being studied to help reduce the prevalence of this disease. The main advantage of protein subunit vaccines is their high degree of safety although this is traded off with the requirement for multiple booster doses to achieve complete protection. Although in certain populations the booster dose can be difficult and costly to administer, development of delayed vaccine delivery techniques, such as a vaccine capsule, could be the solution to this problem. One of the main drawbacks in this technology is that the antigen must remain stable at body temperature (37 °C) until release is achieved. Here we elucidate the stability of a recombinant chlamydial major outer membrane protein (MOMP) antigen and assess its antigenic and immunogenic properties after subjecting the antigen to 37 °C for four to six weeks. Through in vitro and in vivo assessment we found that the aged chlamydial MOMP was able to produce equivalent humoral and cell-mediated immune responses when compared with the unaged vaccine. It was also found that vaccines formulated with the aged antigen conferred equivalent protection against a live infection challenge as the unaged antigen. Thus ageing chlamydial MOMP antigens at 37 °C for four to six weeks did not cause any significant structural or antigenic/immunogenic degradation and recombinant C. muridarum MOMP is suitable for use in a delayed vaccine delivery system., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Despite the success of combination antiretroviral therapy (cART) in HIV treatment, a cure for HIV remains elusive. Scientists postulate that HIV latent reservoirs may be a vital target in curative strategies. Vorinostat is a latency-reversing agent that has demonstrated some effectiveness in reactivating latent HIV, but complementary therapies may be essential to enhance its efficacy. One such approach may utilize the CRISPR-Cas9 system, which has evolved to include transcriptional activators such as dCas9-VPR. In this study, we explored the effects of combining vorinostat coupled with gesicle-mediated delivery of dCas9-VPR in promoting the transcription of integrated HIV proviruses in HIV-NanoLuc CHME-5 microglia and J-Lat 10.6 lymphocytes. We confirmed that dCas9-VPR ribonucleoprotein complexes can be packaged into gesicles and application to cells successfully induced HIV transcription through interactions with the HIV LTR. Vorinostat also induced significant increases in proviral transcription but generated inhibition of cellular proliferation (microglia) or cell viability (lymphocytes) starting at 1,000 nM and higher concentrations. Experiments combining dCas9-VPR gesicles and vorinostat confirmed the enhanced transcriptional activation of the HIV provirus in microglia but not lymphocytes. Thus, a combination of dCas9-VPR gesicles with other latency-reversing agents may provide a complementary method to activate latent HIV in future studies utilizing patient-derived cells or small animal models., Competing Interests: The authors declare no competing interests., (© 2024 The Authors.)

Importance: Our study addresses a significant issue in the medical and scientific community-the delayed administration of appropriate antimicrobial treatments due to the time-consuming process of phenotypic susceptibility data collection in gram-negative bloodstream infections. Our research indicates that a multiplex PCR rapid diagnostic test (RDT) significantly outperformed two clinical scoring tools in predicting ceftriaxone susceptibility. Multiplex PCR also led to reduced instances of undertreatment with ceftriaxone and minimized overtreatment with carbapenems. Furthermore, multiplex PCR demonstrated high sensitivity and specificity in predicting ceftriaxone susceptibility. The results of our study underscore the potential RDTs to reduce the time to appropriate antimicrobial therapy, leading to improved patient outcomes and reduced healthcare costs., Competing Interests: Tristan T.

Importance: Bacterial resistance to antibiotics is a crisis. Acinetobacter baumannii is among the CDC urgent threat pathogens in part for this reason. Lipopeptides known as turnercyclamycins are produced by symbiotic bacteria that normally live in marine mollusks, where they may be involved in shaping their symbiotic niche. Turnercyclamycins killed Gram-negative pathogens including drug-resistant Acinetobacter , but how do the mechanisms of resistance compare to other lipopeptide drugs? Here, we define resistance from a truncation of MlaA, a protein involved in regulating bacterial membrane phospholipids. Intriguingly, this resistance mechanism only affected one turnercyclamycin variant, which differed only in two atoms in the lipid tail of the compounds. We could not obtain significant resistance to the second turnercyclamycin variant, which was also effective in an infection model. This study reveals an unexpected subtlety in resistance to lipopeptide antibiotics, which may be useful in the design and development of antibiotics to combat drug resistance., Competing Interests: E.W.S., B.W.M., and M.G.H. have filed a patent application for turnercyclamycins.

Background: Cutibacterium acnes is a common commensal of human skin but may also present as an opportunistic pathogen in prosthetic joint and wound infections. Unfortunately, few complete genomes of C. acnes are publicly available, and even fewer are of isolates associated with infection. Here we report the isolation, characterization, and complete genomes of 2 C. acnes isolates from a surgical site infection of an elbow., Methods: We used standard microbiological methods for phenotypic characterization and performed whole genome sequencing on 2 C. acnes isolates using a combination of short-read and long-read sequencing., Results: Antibiotic susceptibility testing showed beta-lactamase negative and low minimal inhibitory concentrations to all antibiotics tested, with the exception of metronidazole. We assembled complete genomes of the 2 isolates, which are approximately 2.5 megabases in length. The isolates belong to the single-locus sequence type (SLST) H1 and the multi-locus sequence type (MLST) IB. Both isolates have similar composition of known virulence genes, and we found no evidence of plasmids but did find phage-associated genes. Notably, the 2 genomes are 99.97% identical but contain a large genomic inversion encompassing approximately half of the genome., Conclusions: This is the first characterization of this large-scale genomic inversion in nearly identical isolates from the same wound. This report adds to the limited numbers of publicly available infection-associated complete genomes of C. acnes ., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2023 Pathogens and Immunity.)

Human capital development is one of the goals of higher education and a decrease in open dialogue threatens these ideals and aspirations. A recent survey of undergraduate students showed that many students censor their point of view. There are many potential reasons for this, but it could be secondary to the current sociopolitical climate. Having educators who encourage and model open dialogue while supporting diversity of thought would provide alternative perspectives and innovation. Encouraging diversity of thought will enhance understanding of other's perspectives and unleash creative problem solving to address concerns in nursing practice and facilitate innovative research. The purpose of this article is to present strategies that can be employed to promote diversity of thought among nursing students in a learning environment. Exemplars are presented illustrating some of the strategies discussed., Competing Interests: Declaration of competing interest None., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Introduction: Ehlers Danlos syndrome (EDS) is a heritable disorder of the connective tissue usually inherited as an autosomal dominant trait. We observe an enrichment of EDS cases in a gastroparesis clinical study., Methods: We explored the frequency of EDS cases in 2 consecutive gastroparesis clinical studies. To explore the genetic surrogates of EDS, we have performed whole-genome sequencing analysis and we focused the analyses on the frequencies of consequential variants in core EDS genes., Results: We report a significant enrichment of EDS cases in a set of patients with gastroparesis (14/686 vs 1/5,000 OR 104 (confidence interval 13.7-793.3) P value <0.0001). We report a significant enrichment of variants in EDS genes in patients with idiopathic gastroparesis., Discussion: The enrichment may be suggestive of converging pathways at the heart of etiology or predisposing patients to EDS with gastroparesis., (Copyright © 2023 The Author(s).

Background: This study involving non-compliant, seized dogs entering the UK surveyed endoparasites detected in faecal samples. A focus was placed on taeniid infection as the detection of these tapeworms acts as a marker for failure of effective tapeworm treatment., Methods: Individual faecal samples taken from 65 dogs over a 24-month period were examined for helminth eggs, for protozoal oocysts and cysts, using a centrifugal flotation technique. Any sample presenting positive results for taeniid eggs had residual faeces examined using polymerase chain reaction to aid speciation of the tapeworm eggs. Additionally, a Baermann technique was used to assess faeces for lungworm larvae., Results: Patent endoparasite infection was detected in 27.7% of dog faecal samples. No sample was positive for lungworm larvae. Five dogs were co-infected with Isospora spp. and Toxocara canis . One dog sample was detected with taeniid eggs, identified as Taenia serialis ., Conclusions: The taeniid-positive dog indicated that appropriate tapeworm treatment may not have occurred, reinforcing the risk to the UK of illegally imported dogs potentially introducing Echinococcus multilocularis infection., Competing Interests: The authors declare they have no conflicts of interest., (© 2023 The Authors.

Background: Non-pathogen reduction platelet bacterial risk control strategies in the US FDA guidance include at least one culture. Almost all of these strategies have a culture hold time of ≥12 h. Studies have reported time to detection (TTD) of bacterial cultures inoculated with bacteria from contaminated platelets, but these data and estimates of risk associated with detection failures have not been synthesized., Methods: We performed a literature search to identify studies reporting TTD for samples obtained from spiked platelet components. Using extracted data, regression analysis was used to estimate TTD for culture bottles at different inoculum sizes. Detection failures were defined as events in which contaminated components are transfused to a patient. We then used published data on time of transfusion (ToT) to estimate the risk of detection failures in practice., Results: The search identified 1427 studies, of which 16 were included for analysis. TTD data were available for 16 different organisms, including 14 in aerobic cultures and 11 in anaerobic cultures. For inocula of 1 colony forming unit (CFU), the average TTD for aerobic organisms was 19.2 h while it was 24.9 h in anaerobic organisms, but there was substantial overall variation. A hold time of 12 versus 24 h had minimal effect for most organisms., Conclusion: TTD variation occurs between bacterial species and within a particular species. Under typical inventory management, the relative contribution of culture detection failures is much smaller than the residual risk from sampling failures. Increasing the hold period beyond 12 h has limited value., (© 2022 AABB.)

Introduction: Early or mid-career physicians have few opportunities to participate in career development programs in health policy and advocacy with experiential and mentored training that can be incorporated into their busy lives., Aim: The Society of General Internal Medicine (SGIM) created the Leadership in Health Policy (LEAHP) program, a year-long career development program, to prepare participants with a sufficient depth of knowledge, skills, attitudes, and behaviors to continue to build mastery and effectiveness as leaders, advocates, and educators in health policy. We sought to evaluate the program's impact on participants' self-efficacy in the core skills targeted in the curriculum., Setting/participants: Fifty-five junior faculty and trainees across three scholar cohorts from 2017 to 2021., Program Description: Activities included workshops and exercises at an annual meeting, one-on-one mentorship, monthly webinars and journal clubs, interaction with policy makers, and completion of capstone projects., Program Evaluation: Self-administered, electronic surveys conducted before and following the year-long program showed a significant improvement in mean self-efficacy scores for the total score and for each of the six domains in general knowledge, teaching, research, and advocacy in health policy. Compared to the baseline scores, after the program the total mean score increased from 3.1 to 4.1, an increase of 1.1 points on a 5-point Likert scale (95% CI: 0.9-1.3; Cohen's D: 1.7), with 61.4% of respondents increasing their mean score by at least 1 point. Responses to open-ended questions indicated that the program met scholars' stated needs to improve their knowledge base in health policy and advocacy skills., Discussion: The LEAHP program provides an opportunity for mentored, experiential training in health policy and advocacy, can build the knowledge and amplify the scale of physicians engaged in health policy, and help move physicians from individual patient advocacy in the clinic to that of populations., (© 2022.

Jet Lag Disorder is a Circadian Rhythm Sleep-Wake Disorder resulting from a misalignment of the endogenous circadian clock and the sleep and wake pattern required by a change in time zone. Jet lag is most severe following eastward travel. This multicenter, randomized, placebo-controlled clinical trial (JET) assessed the physiological mechanism of jet lag induced by a real-life transmeridian flight and evaluated the efficacy of tasimelteon-a circadian regulator acting as a dual melatonin receptor agonist, in the treatment of Jet Lag Disorder (JLD). Tasimelteon-treated participants slept 76 min longer on Night 3 during their second trip (evaluation phase) as compared to their first (observational phase). Over the three travel nights evaluated, transmeridian jet travelers in the tasimelteon group slept 131 min more (TST 2/3 ) than those in the placebo group. The JET study demonstrated clinically meaningful improvements in nighttime sleep and daytime alertness in both objective and subjective measures as well as global functioning after a real-world flight. These results suggest that tasimelteon can be an effective therapeutic tool to treat JLD in the context of transmeridian travel., Competing Interests: Authors CP, VP, EC, MF, SS, CX, GB, and MP are employees of Vanda Pharmaceuticals Inc.

Introduction: Life-threatening infections such as infective endocarditis (IE) are increasing simultaneously with the injection drug use epidemic in West Virginia (WV). We utilized a newly developed, statewide database to describe epidemiologic characteristics and healthcare utilization among patients with (DU-IE) and without (non-DU-IE) drug use-associated IE in WV over five years., Materials and Methods: This retrospective, observational study, incorporating manual review of electronic medical records, included all patients aged 18-90 years who had their first admission for IE in any of the four university-affiliated referral hospitals in WV during 2014-2018. IE was identified using ICD-10-CM codes and confirmed by chart review. Demographics, clinical characteristics, and healthcare utilization were compared between patients with DU-IE and non-DU-IE using Chi-square/Fisher's exact test or Wilcoxon rank sum test. Multivariable logistic regression analysis was conducted with discharge against medical advice/in-hospital mortality vs. discharge alive as the outcome variable and drug use as the predictor variable., Results: Overall 780 unique patients had confirmed first IE admission, with a six-fold increase during study period (p = .004). Most patients (70.9%) had used drugs before hospital admission, primarily by injection. Compared to patients with non-DU-IE, patients with DU-IE were significantly younger (median age: 33.9 vs. 64.1 years; p < .001); were hospitalized longer (median: 25.5 vs. 15 days; p < .001); had a higher proportion of methicillin-resistant Staphylococcus aureus (MRSA) isolates (42.7% vs. 29.9%; p < .001), psychiatric disorders (51.2% vs. 17.3%; p < .001), cardiac surgeries (42.9% vs. 26.6%; p < .001), and discharges against medical advice (19.9% vs. 1.4%; p < .001). Multivariable regression analysis showed drug use was an independent predictor of the combined outcome of discharge against medical advice/in-hospital mortality (OR: 2.99; 95% CI: 1.67-5.64)., Discussion and Conclusion: This multisite study reveals a 681% increase in IE admissions in WV over five years primarily attributable to injection drug use, underscoring the urgent need for both prevention efforts and specialized strategies to improve outcomes., Competing Interests: The authors have declared that no competing interests exist.

Objective: Hidradenitis suppurativa (HS) is a chronic autoinflammatory skin disease with a higher prevalence in women. The disease results in a low quality of life as well as physical and psychological comorbidities. The authors sought to determine the effects of HS on women's self-perception and life experiences., Methods: Semistructured interviews were conducted with 22 women of varying age and family status. The content was transcribed and subjected to both thematic and content analyses., Results: Five themes and a number of subthemes were revealed, involving physical, emotional, coping, and functional aspects. Somatic features, especially pain, were the most troubling issues, along with the emotional burden of shame and loss of femininity and intimacy. However, women also revealed strength and expressed optimism., Conclusions: These findings reveal the inner world of women coping with HS, addressing multiple dilemmas, problems, and concerns. Healthcare providers should pay special attention to the specific needs of these patients. Additional research is needed to further shed light on the impact of HS on women., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)

Infectious diseases like infective endocarditis (IE) may manifest or progress differently between sexes. This study sought to identify the differences in demographic and clinical characteristics among male and female patients with IE. Data were obtained from a newly developed registry comprising all adult patients with first IE admission at the four major tertiary cardiovascular centers in West Virginia, USA during 2014−2018. Patient characteristics were compared between males and females using Chi-square test, Fisher’s exact test, and Wilcoxon rank-sum test. A secondary analysis was restricted to IE patients with drug use only. Among 780 unique patients (390 males, 390 females), significantly more women (a) were younger than males (median age 34.9 vs. 41.4, p < 0.001); (b) reported drug use (77.7% vs. 64.1%, p < 0.001); (c) had tricuspid valve endocarditis (46.4% vs. 30.8%, p < 0.001); and (d) were discharged against medical advice (20% vs. 9.5%, p < 0.001). These differences persisted even within the subgroup of patients with drug use-associated IE. In a state with one of the highest incidences of drug use and overdose deaths, the significantly higher incident IE cases in younger women and higher proportion of women leaving treatment against medical advice are striking. Differential characteristics between male and female patients are important to inform strategies for specialized treatment and care.

Several common adverse pregnancy outcomes can reveal subclinical or latent cardiovascular disease (CVD) risk, transiently exposed through the physiologic stress of pregnancy. The year after pregnancy may be a singular opportunity to identify and initiate treatment for CVD risk, even before the onset of traditional CVD risk factors. However, clinical guidance regarding CVD risk management after adverse pregnancy outcomes is lacking. We therefore conducted a systematic review of US clinical practice guidelines and professional society recommendations to inform primary care-based CVD risk management after adverse pregnancy outcomes. We identified 13 relevant publications. While most recommendations were based on limited or weak evidence, we identified several areas of consensus. First, individuals with an adverse pregnancy outcome associated with future CVD are likely to benefit from CVD risk assessment-accompanied by education, counseling, and support for lifestyle modification-beginning within the first postpartum year. Second, among clinicians, clear and consistent documentation about adverse pregnancy outcomes and recommended follow-up is important to coordinate care after pregnancy. In addition, patients need to be informed about their pregnancy complications and associated CVD risks, so that they can make informed health care and lifestyle decisions. Finally, in general, CVD prevention in the year after an adverse pregnancy outcome focuses on lifestyle modification, reserving pharmacotherapy for the highest-risk patients and those with traditional CVD risk factors. While postpartum lifestyle interventions show promise for reducing CVD risk after adverse pregnancy outcomes, continued research to determine the optimal content, timing, and long-term effects of such interventions is needed., (© 2021.

Objective: Phototherapy is a well-established therapy in dermatology. However, there is limited evidence regarding phototherapy for the treatment of generalized pruritus of unknown origin (GPUO). The objective of this study was to assess the efficacy and safety of narrowband ultraviolet B (NB-UVB) phototherapy in patients with GPUO., Methods: Researchers conducted a retrospective review of the treatment outcomes of patients with GPUO who were treated with NB-UVB between 2004 and 2019 at their facility., Results: Investigators included 67 patients diagnosed with GPUO treated with NB-UVB. Complete remission was achieved in more than 70% of the patients. No serious adverse events were documented., Conclusions: For patients with GPUO, NB-UVB may be a safe and effective treatment option., (Copyright © 2022 Wolters Kluwer Health, Inc.

Purpose: To assess the efficacy of tasimelteon to improve sleep in Smith-Magenis syndrome (SMS)., Methods: A 9-week, double-blind, randomized, two-period crossover study was conducted at four US clinical centers. Genetically confirmed patients with SMS, aged 3 to 39, with sleep complaints participated in the study. Patients were assigned to treatment with tasimelteon or placebo in a 4-week crossover study with a 1-week washout between treatments. Eligible patients participated in an open-label study and were followed for >3 months., Results: Improvement of sleep quality (DDSQ50) and total sleep time (DDTST50) on the worst 50% of nights were primary endpoints. Secondary measures included actigraphy and behavioral parameters. Over three years, 52 patients were screened, and 25 patients completed the randomized portion of the study. DDSQ50 significantly improved over placebo (0.4, p = 0.0139), and DDTST50 also improved (18.5 minutes, p = 0.0556). Average sleep quality (0.3, p = 0.0155) and actigraphy-based total sleep time (21.1 minutes, p = 0.0134) improved significantly, consistent with the primary outcomes. Patients treated for ≥90 days in the open-label study showed persistent efficacy. Adverse events were similar between placebo and tasimelteon., Conclusion: Tasimelteon safely and effectively improved sleep in SMS., (© 2021. The Author(s).)
